Construction:

Conductor:Sizes 6 - 4/0 AWG: Class K, flexible stranded, bare copper per ASTM B3 and B172.
Sizes 250 - 1000 kcmil: Class I, flexible stranded, bare copper per ASTM B3 and B172.
Insulation: Cross Linked Polyethylene (XLPE) Type RHH/RHW-2

Applications and Features:

Southwire’s 2000 Volt power cables are suited for use in the internal wiring of Battery Energy Storage Systems (BESS), in wet and dry locations, conduits, ducts, troughs, covered trays, and where superior electrical properties are desired. These cables are capable of operating continuously at the conductor temperature not in excess of 90°C for normal operation, 130°C for emergency overload, and 250°C for short circuit conditions. Gasoline and Oil Resistant. For CT USE sizes 1/0 AWG and larger. Rated 1000 lb/ft maximum sidewall pressure.

Also available in different colors like: black, red, green, brown, yellow, etc.

Specifications:

ASTM B3 Soft or Annealed Copper Wire

ASTM B172 Standard Specification for Rope-Lay-Stranded Copper Conductors Having Bunch-Stranded Copper Conductors

UL 44 Thermoset-Insulated Wires and Cables

UL 1685 Vertical-Tray Fire Propagation and Smoke Release Test

RoHS-3 Complies with European Directive 2015/863
